TECHNICAL CERAMICS

Technical Ceramics covers ceramic materials and products for technical application. Terms such as:

• functional ceramics
• structural ceramics
• engineering ceramics
• industrial ceramics
• high-performance ceramics
• electro-ceramics
• cutting ceramics
• bio-ceramics

describe the products groups of Technical Ceramics, but due to overlapping do not allow a clear classification.

FUNCTIONAL CERAMICS

Components which fulfill an electrical, magnetic, dielectrical, optical etc. function belong to this group.

STRUCTURAL CERAMICS (INDUSTRIAL CERAMICS; ENGINEERING CERAMICS)

Components which are subjected mainly to mechanical loads (tensile and pressure strain, bending moments etc.) fall under the category structural ceramic. Sometimes the terms industrial or engineering ceramics are also used for these products.

HIGH-PERFORMANCE CERAMICS

In ENV 12212 high-performance ceramics are defined as "highly developed, high-performance applicable ceramic material, which is mainly non-metallic and inorganic, and has certain functional properties." The term is seen as a differentiation to traditional clay based ceramic that includes china-ware, sanitary ceramic tiles and bricks and covers all technical ceramics. The materials for electrical engineering are standardised in IEC 627.

MATERIAL GROUPS OF TECHNICAL CERAMICS

The term used above are often still used in classify technical ceramics. However an unambiguous classification is only possible if the materials are listed under their chemical composition:

• silicate ceramics
• oxide ceramics
• Nonoxide ceramics: carbide, nitride,
